Hi dear brothers,
i have problem with mitsubishi ducted split - model PEY48 indoor /PUY-P48VAK outdoor

actually couple of month back we faced on cyclone heavy rain with heavy wind in oman,
the outdoor unit fell down on the heavy wind throw , after that we got some problem in the ac outdoor unit...

in the PCB power board IGBT burned, so then we order new Power board and install
but again the IGBT burned on the same location on new board now we confused why

when we install new board the compressor running few minits only

someone help me to sortout the problem....
